Ah, a real Christmas tree! There's nothing quite like the scent of a fresh pine tree in your home during the holiday season. To keep your tree fresh, make sure to give it plenty of water. Keep the stand filled and change the water daily if possible. Also, try to keep the tree away from heat sources such as fireplaces or radiators. Finally, don't forget to add a bit of tree preservative to the water, which will help keep the tree hydrated and green for longer.
